Question

I need the answer of this question as quick as possible.please someone give me the answer

Answer 1

the formula is I = 1/2 × [(concentration of Nacl in M × # of sodium ions × (charge of sodium)2) + (concentration of Nacl in M × # of cl ions × (charge of cl)2) + (concentration of na2so4 × # of sodium ions × (charge of sodium)2) + (concentration of na2so4 in M × # of so4 ions × (charge of chloride)2)]
